Patented July 19, 1910.

To all whom it may concern:

Be it known that I, \VILLIAM D. MOUNT, a citizen of the United States,residing at Saltville, in the county of Smyth and State of Virginia,have invented certain new and useful Improvements in Barrel-Heaters, ofwhich the following is a full, clear, and exact description.

This invention relates to special heating appliances, and moreparticularly to a keg and barrel heater, and has for its object theprovision of means for increasing the capacity of barrel making plants.

In the process of making barrels it is customary after the staves h avebeen set up and while temporarily held by the assembling rings, to heatthem while in position upon drum stoves and thereby give them theirpermanent set and my invention provides an apparatus by means of whichthis heating operation, as applied to successive barrels, can be acontinuous one, the barrels being placed in position upon a travelingheater; and hence the different stages of heating and, if need be, ofcooling can be conducted simultaneously.

In large factories, numbers of stoves are required necessitatingconsiderable floor space or room, and the presence of a number ofoperatives to manipulate the assembled staves which have to be movedtoward and from the stoves, which latter are frequently, especially if alarge number be used, somewhat remote from the stave assembler.

My device is adapted for use in plants of any capacity and necessitatesusually, in practice, but one or two operatives therefor; suchoperatives not being ordinarily obliged to move from their respectivestations.

Various other novel features of my in vention will be hereinafterdescribed, and particularly set forth in the annexed claims.

Referring to the drawings which form a part hereof, and in which likereference characters designate like parts throughout the several views:Figure 1 is an axial section through my barrel heater; Fig. 2 is a planof the same, the chimney being shown in section, said section havingbeen taken on the line II-II of Fig. 1. Fig. 3 is a section taken on theline IH TII of Fig. 1 in order to better illustrate the mechanismemployed for rotating the carrier.

Upon a fixed base 1 is rotatably mounted a circular frame 2; ballbearings 3 being provided between the said frame and base in order toreduce friction and render the device readily manipulatable. The frame 2carries a polygonal casing or box 1, the bottom of which is preferablygrated as shown at 5. A cover 6 is provided, preferably having flanges 7for engagement with the upper edge of the said box, said cover havingtherein a plurality of apertures 8 centrically disposed about the axisof the device.

In the embodiment of my invention herein set forth, the polygonal casingis hexagonal in form, and a plurality of flanged cylindrical shells ormembers 9 are disposed opposite the respective faces of the hexagonalcasing; the flanges 10 of said shells contacting with said faces. In theinterior of each of the shells is a partition 11 which I extendsoutwardly through the same from the face of the hexagonal structurethrough substantially three-quarters of the length of the cylindricalprotuberances 9 each of these partitions being preferably in the horizontal plane. Masses of fire clay or other refractory material aredisposed in various portions of the structure above referred to; theclosed end 12 of each of the shells containing a mass 13 of the saidrefractory material; partitions 11 not extending so far through the saidshell as to contact with the said mass. In the bottom of the hexagonalcasing is correspondingly disposed a mass of refractory material 14,such mass being centrally recessed as at 15 and provided with aplurality of semi circular channels or troughs 16 extending radiallyoutward from recess 15. Channels 16 lead into and are substantially ofthe same cross sectional area as the channels 17 formed by the lowerportion of the cylindrical casings aforesaid and their respectivepartitions. A further mass 18 of refractory material is positioned inthe upper portion of the hexagonal casing, such mass being provided witha cylindrical recess 19 extending therethrough and leading into therecess 15 aforesaid. The said mass 18 serves to cover the respectivechannels 16; the line of joint-Lire between refractory masses 14 and 18being substantially in the plane of partitions 11. Finally a plurality,in this instance six, of vents or flues 20 are provided in the mass 18respectively opening into the upper passages 21 which are formed by theupper-portions of casings 9 and partitions 11 and connect passages 21with apertures 8 in cover 6 aforesaid. It

will thus be seen that a plurality of tortuous fines are providedstarting at the ports 8 and successively passing through the passages orconduits 20, 21, 17, 16, 15 and 19.

The cover 6 is centrally flanged as at 22, which flange is received intoa recess in the bottom of a chimney 23. The upper surface of flange 22is disposed almost in contact with the lower portion of a circularlyformed angle-iron 24, which is secured in any proper manner to theinterior of the metallic, cylindrical portion 25 of the said chimney.The interior of the chimney is coated with a layer 26 of refractorymaterial providing an interior space 27 of substantially the samediameter as recess 19 aforesaid. The chimney may be provided withsuitable stiffening and supporting means, such as a flanged ring 28; andis intended to be permanently and non-rotatably fixed in position.Surrounding the chimney in adjacency to the cover plate 6 is an annularair pipe 29, preferably several inches in diameter, the upward extension30 from which is connected to a pressure producing device (not shown);valve 31 being provided in the said pipe to afford control of the blast.Above pipe 29 is a correspondingly disposed gasolene or othercombustible supplying pipe 32, provided in this instance with six setsof downwardly directed pipe sections 33. A plurality of valves 34 arecorrespondingly disposed between said pipe sections, so that a properamount of gasolene may be allowed to descend therethrough, and both theair and gasolene are respectively directed into a plurality of burners35, in this instance six in number in correspondence with the number ofapertures 8 provided therebelow. The mouth 36 of each of said burners isquite adjacent to the aperturecl plate or cover 6, so that the flameemitted by said burners may pass downwardly through the conduits 20 andlaterally outward through conduits 21, around the ends of partitions 11,inwardly through conduits 17 and 16, and finally up the chimney,whenever the said burners come in alinement with any of the said portsor openings 8. It is obvious of course that any number of burners may beemployed, or that the apertures 8 may be of any desired size or shape,so that if desired 'a substantially continuous flame may be playedaround through the interior of the carrying members 9. In practice, Ifind that the arrangement shown affords even more than sufficient heatfor the purpose in question; and that a greater number of burners isunnecessary. When desired certainof the burners may be turned off, sothat the barrels may be heated for a predetermined portion of theirtravel and then allowed to cool to any desired extent before beingremoved from the apparatus.

0001 air will obviously be drawn through the draft passages when theheated medium is not supplied, owing to the draft created by thechimney, due to the heat generated by the burners which are in use. Uponeach of the shells 9, I provide suitable supports 37 which are adaptedto engage the upper portion of the interior of a barrel or of the stavesassembled in the manner aforesaid.

For convenience in removing the stave carriers or shells, in order toclean the same when necessary, or for other purposes, I provide meansfor permitting the ready removal of the same; and the means forattaching the carriers to the respective faces of the hexagonal box orbody, is hence, preferably, simply a plurality of hooks 38 which extendup from the upper portions of said box and engage the correspondinglydisposed apertures 39 in the upper portion of the respective flanges 10of said carriers.

Upon the exterior of the frame 2 are provided a plurality of oppositelydisposed lugs 41-42. Brackets 4343 are carried by the upper portion ofthe base 1, and have slidably mounted therein in suitable guide-ways, abar 44, said bar being held in position upon the said brackets bybracket caps 45. Bar 44 carries a pivotally mounted pawl 46, the notchedend 47 of which is adapted for engagement with lugs 41. Pawl 46 isspring pressed, the spring being shown at 48 suitably secured to anupwardly projecting lug 49 upon the bar 44.

Pivoted at 50 upon bracket 43 is a locking lever 51, said lever beingprovided with a somewhat irregularly shaped cam-slot as shown at 52, inwhich travels a downwardly projecting pin 53 carried by the bar 44. Asshown in Fig. 3, bar 44 is substantially at one end of its stroke, pin53 being at the left hand end of slot 52. If now the said bar be movedto the right, the pin will proceed through the short straight portion 54of slot 52, and will thence proceed through the longer and angularlydisposed portion of the slot, thereby causing the lever to rotateinwardly toward the frame 2. In the interim, the pawl 46, by rotatingframe 2, has advanced the lug 42 which happens to be in adjacency to acorresponding lug' 55, carried by lever 51, so that the said lugs cannotengage; lug 42 having proceeded beyond lug 155 before the latter hasgotten into engaging position. It is evident, however, that thesucceeding lug 42 will ultimately be engaged by lug 55; which willtherefore limit the rotary movement, which the carrying apparatus iscapable of, for any given single actuation thereof. This prevents theapparatus from rotating around continuously or too freely, which isobviously otherwise apt to occur, as all of the rotary parts are mountedon ball bearings as above described. When the bar 44 returns to theposition shown in Fig. 3, lug 55 will be disengaged with itscorresponding lug42, and pawl end l7 will engage with the nextsucceeding lug 41. Bar 4L4 is reciprocated by means of a link 56 whichis pivotally secured thereto at 57, and the other end of which ispivotally connected at 58 to the hand-lever 59. This lever is of anysuitable description, being pivoted to a suitable support at 60 whichmay also carry the usual guard or guide 61.

My device is admirably adapted for the purpose in question, beingcapable of heat ing barrel parts or staves to any desired degree andbeing operable by hand by a single workman without undue effort. Theassembled staves are advanced around upon the carrier step by step, sothat for example the man whose duty is to remove the staves therefrom,may be positioned at a point 62 adjacent the lever 59, and thus notdistant from the operator who is stationed at 63 for the purpose ofplacing the assembled staves upon the machine. As both of the operatorsare hence conveniently positioned with respect to lever 59, either onemay actuate the device, as needed. It will thus be seen that theassembled staves may be dried through an interval of time which issubstantially equal to that necessary to assemble the staves of sixbarrels; and this I find in practice fully suiiices to satisfactorilydry out the staves, giving them their proper set.

I may point out in conclusion, that the movement-limiting device servesalso to aline the burners with apertures 8 when the carrier is not beingrotated.
